The film also had a big influence on Hayao Miyazaki. Here's a DVD Review (some interesting comments at the bottom). The film is one of the great classics of European animation, but the French have this nasty, annoying habit of keeping their best films to themselves and not releasing them in the English-speaking world. Hence, there is no actual DVD available of the real version of the film with English subtitles (though there are some cheapie dollar-store DVDs of the 1952 version dubbed with English voices).
By the way, here's another "trailer" from the Prince Vladimir film that was released this February... shame that it's on Youtube and at low quality, but it does show some hints of some really good animation (check out that flying-camera scene 2 minutes in) and show that it's a pretty dark film (much of the audience was dismayed to find that it's not really suitable for children, apparently). This is another one that unfortunately probably won't be released with English subtitles. Even the high-profile European animated films tend to stay in Europe, and often never even leave the country where they were made (especially true of Russia).
